angular - "@angular/compiler-cli"软件包未正确安装错误

Question

我正在尝试使用 ng build 构建我的 angular2 应用程序，但出现以下错误:-

The "@angular/compiler-cli" package was not properly installed. Error: TypeError: Object prototype may only be an Object or null: undefined

我什至尝试删除现有的node_modules并再次安装，但没有成功。

有什么想法吗？这是我的 package.json:-

    "@angular/common": "2.4.6",
    "@angular/compiler": "2.4.6",
    "@angular/core": "2.4.6",

您可以卸载、清理缓存并更新最新版本的 Angular

npm uninstall -g angular-cli @angular/cli
